Walk the line with this...

Musical superstars Sheryl Crow, Foo Fighters, Shooter Jennings & Jessi Colter, Norah Jones, Kid Rock, Alison Krauss, Kris Kristofferson, Jerry Lee Lewis, Martina McBride, Brad Paisley, U2 and Dwight Yoakam perform tonight on "I Walk the Line: A Night for Johnny Cash," to honor country music legend Johnny Cash.  Joaquin Phoenix, Reese Witherspoon and Dennis Quaid introduce the performances. The special was taped at the Pantages Theater in Hollywood

By far, the standout performance is from Kid Rock and Jerry Lee Lewis singing "I Walk the Line," which received the only standing ovation of the evening.

By far the most glaring omission of the evening - a performance by Willie Nelson.

Tune in tonight at 8:00PM ET/PT on CBS.  If you watch closely, you might catch a glimpse of a tallglassofmilk in the audience.
